1. Chapter 6: Modeling Problems by Alex Calloway , Ray Bandas & Sabina Maza

4. Modeling Tools can be used to model population growth, such as colonies after a hurricane, or citizens in a new country. Visualization tools can be used to graph things such as the descent of a shuttle, or the setting of the sun. Systems modeling tools are especially effective for modeling problems because learners can test their models for accuracy. Jonassen again uses the example of a molar conversion problem in chemistry in the text. An additional example of a systems modeling tool could track the new citizens in a country. Finally, visualization tools are helpful for modeling abstract concepts like mathematic problems. Visualization can be used to plot the descent of a shuttle or the setting of the sun.
